" ooE -rLA TEE ATTACHMENT.

To all whom it may concern:

Be it known that we, AUGUST W. BLANK and EMIL BLANK, citizens of theUnited States, residing at WVebster, in the county of Day and State ofSouth Dakota, have invented new and useful Improvements in Corn-PlanterAttachments,

attachment which may be easilyand conveniently thrown into to interruptthe planting whenever and out of gear so as desired, such as when theturn is being made at the end of the row.

A further object of the invention is ,to pro vide a check row attachmentincluding simple and improved means whereby the point at which to beginoperations at the beginning of a row maybe correctly ascertained;

Vith these and other ends in view which will readily appear asthe natureof the invention is better understood, the same consists in the improvedconstruction and novel arrangement and combination of parts which willbe hereinafter fully described and particularly pointed out in theclaims. 7

In the accompanying drawings has'been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made tothe precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired. i In the drawings,Figure 1 is alongitudinal sectional view of a machine constructed in accordance withtheinvention. Fig. 2 is a longitudinal vertical Sectional view taken ona'diiferent plane. Fig. 3 is a perspective detail view of the gage wheelwhich constitutes a part of the improved check row attachment, Fig. 1 isa sectional detail view taken on theline ttin 1.

of the seed shaft, together with the forward end of the actuating rod,the latter being detached from the crank.

Corresponding parts in the several figures are denoted by The: mainframe of the planter is supported on the axle B having the groundengaging wheels C. The runner frame D which is pivotally supported at Ecarries the runners F, the seed boxes or hoppers G like charactersofreference.

and the seed dropping mechanism which,

includes a rock shaft H which is actuated in one direction by a Spring5. The mainframe carries a seat J for thedriver or operator, andsuitably'mounted on said main frame is the customary hand lever runnerframe may be raised or lowered. v

The. improved check row attachmentincludes a frame having side members10, the forward ends of which are bolted orotherwise secured on aflange: 11. formed on a sleeve or boxing 12 which is loosely mounted onthemain axle I3 of the machine, said sleeve being secured againstdisplacement longitudinally of the axle by means of collars 13 havingset screws 14 whereby they are secured in position. ends of the sidebars 10 are boxes 15 affording bearings for a shaft 16, said shaft hav-Bolted on the rear K whereby the T ing intermediate its ends a squaredor non- I circular portion 17 and near one end another squared ornon-circular, portion 18, said non-circular portions supporting,,re-'spectively, the operating wheel 19 and the tappet wheel 20. Washers 21'having flanges 22 that embrace the boxes 15 serve to properly space theparts on the of which ;is equal to the required distance between thehills,

ner that no portion of said" marker will pro ject beyond the perimeterof the wheel,

is provided with a' recess whereln a marker 25 is seated in such a manitends laterally offering no obstruction to the operation of the scraper26 which is supported by a rod 27 connected with one of the frame bars10. It is obvious that the operating wheel must be so positioned thatthe marker 25 will engage the ground to make the mark at the exact timewhen the seed is dropped by the seed dropping mechanism in advance ofthe operating wheel, and also that the mark made by the operating wheelmust be precisely one hill in rear of the hills which are being planted,although located intermediately therebetween. In order that adjustmentwith this end in View may be properly made it is desirable that theboxes 15 be adjustably connected with the side members 10 by providinglongitudinal slots for the passage of the bolts or fastening members 28.l, a, 1,

An operating rod or bar 29a provided aving near its front end a T-shapednotch 30 adapted to engage a crank 31 on the rock shaft H whichconstitutes the operating shaft of the seed dropping mechanism. The rod29 is supported in a stirrup 31 carried by a spring 32 which has beenshown as be ing suspended by means of a linkrod 33 beneath the driversseat J; it being, however, of course, understood that a separatesupporting bracket may be provided when required. The rear end of therod or bearing 29 has a concave recess 34 which is disposed in the pathof the tappet 35 that exfrom the tappet wheel 20 so that by eachrotation of said tappet wheel, the rod 29 will. be pushed or moved in aforward direction, thereby actuating the rock shaft ,H against thetension of the spring 5, which latter serves to restore said rockshaftrto its initial position when the rod 29 is released fromengagement with the 'tappet, the rod 29 being then retracted by thespring 32, whereby it is resiliently supported for a repetition of theope ation, I v For the purpose of lifting the operating frame to movethe operating wheel clear of the ground for the vpurpose of interruptingthe planting, means, are provided including a lever 36 fulcrumed at 37on a stand which includes a rack segment 38 which isengag ed by a stopmember ,39 carriedby the lever. Pivotally connected with the hand lever36 is one end of a lifting rod 39', the other end of which is guidedthrough a lug 40 on one of the side bars 10 andis, provided with aterminal stop memberfl-l, thus enabling the operating frame to be liftedby means of the lever 36. Coiled on the lifting, rod 391between the lug40 and a stop collar 42 is a spring 43, the tension of which-is exertedto force the operating frame and the operating wheel in thedirection ofthe ground, holding the rim of the operating wheel in ground v i n itiwith sufficient force to insure the rotation of the wheel when themachine is in operation, but not sufficiently to prevent the wheel frompassing over stones and other obstructions in the path thereof. The rearcross bar 44 of the planter frame has been shown as being provided withan arch 45 or upwardly offset portion to accommodate the gage Wheel whenthe operating frame is elevated to throw the planting mechanism out ofoperation'.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood by those skilled in the art to which it appertains.It will be seen that by this attach; ment which is simple inconstruction and substantially automatic in its operation, the i use ofthe chains heretofore employed to actuate check rowcorn planters may bedispensed with, thereby avoiding the labor and annoyance of shifting thechains at the end of each row and at the same time enabling the corn tobe planted in check rows with the utmost accuracy and certainty and without constant supervision on the part of the driver who is, merelyrequired to marks made 3 machine. p In applying the improvement tovarious types of corn planters various minor changes may be required,but such changes will be held to be within the scope of the appendedclaims. v v

,Having thus described the invention, what is claimed as new, is p 1.The combination with a corn planter having an operating shaft supportedfor oscillation, and a retracting spring for said shaft, of a check rowattachment including a frame supported pivotally on the axle of themachine, a shaft supported on said frame, an earth engaging operatingwheel and a tappet wheel carried by said shaft, said tappet wheel havinga laterally extending tappet, a resiliency supported stirrup carried bythe planter frame, a crank on the operating shaft of the planter, and anoperating rod supported in the stirrup, said operating rod beingconnected at its forward end with the crank on the operating shaft andhaving its rearward end disposed in the path of the tappet. 4
